Jennifer Lopez

Jennifer Lopez kicked off the past 12 months by announcing that she was stepping down from her hosting duties on American Idol. Her decision has allowed her to return to the world of film with Parker and get back to her music career with her new single, "Live It Up." However, J Lo hasn't fully left the world of television, as she announced back in September that she would be joining nuvoTV to help with program development and marketing for the network. Jennifer also just signed on for The 33, a film that follows the true story of the rescue of the Chilean miners in 2010.
